Event Data
The event handler receives an argument of type QueryItemsEventArgs containing data related to this event. The following QueryItemsEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| AsyncQueryInfo | Gets an AsyncQueryInfo that provides the information necessary to retrieve the next batch of items. |
| CollectionView | Gets the DataGridVirtualizingCollectionView to which the grid is bound. |
| GroupPath | Gets a read only collection of DataGridGroupInfo objects, which provide information on the parent groups. |
| IsAsync | true if the event is asynchronous, otherwise false. By default, true. (Inherited from Xceed.Wpf.DataGrid.AsyncQueryEventArgs) |
Remarks
Unlike the QueryItemCount and QueryItems events, which must both be handled, the AbortQueryItems event is not required. If it is not handled, calls to the EndQuery method for blocks of data that are no longer needed will be ignored.
